Yeah.  I tried to reproduce this on the gcc compile farm's Solaris 10
machine, but the test passed fine for me.  The only obvious configuration
difference I can find is that that machine has

$ cc -V
cc: Sun C 5.10 SunOS_sparc Patch 141861-10 2012/11/07

whereas castorides' compiler seems to be a few years older.  So this
does seem like it could be a compiler bug.
